BICYCLE-LOCK.

SPECIFICATION forming part of Letters Patent No. 550,536, dated November 26, 1895.

Application led August 29, 1895.

T0 all whom t may concern.-

Be it known that I, JAMES E. SCOTT, a citizen of the United States, and a resident of Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Bicycle- Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure l of the drawings is a representation of the invention applied to a bicycle, the front portion of the latter being removed. Fig. 2 is a fragxnental view of a bicycle, also showing the application of the invention. Fig. 3 is a face view of the lock, the bolt protracted. Fig. ais a similar view with coverplate removed. Fig. 5 is a section on line Fig. 6. Fig. 6 is a section on line y y, Fig. 5, the cover-plate in place. Fig. 7 is asimilar view on line z a', Fig. et. Fig. 8 is a section on line w yw, Fig. 3. Fig. 9 is a view of the key.

The object of this invention is to provide a simple, inexpensive, and efficient lock of novel character for bicycles and the like; and the invention consists in the novel construction and combination of parts, all as hereinafter described, and pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates the case or shell of the lock, which is formed with a removable cap-plate or cover B. O designates a lockingbolt, which is fitted to slide or reciprocate longitudinally within the said case or shell, its locking end portion being arranged to be projected outwardly through a circular opening a in one end of the case or shell. E is a spring which is coiled around a reduced portion of the said bolt, having a bearing at one end against a collar b thereof and at its other end against an abutment of the case or shell. Fixed in the said bolt is a pin d, which projects through an oblong slot e in the said cap or cover plate and has upon its outer end a knob or button E. Formed in the under side of the bolt is a transverse notch f, which when the bolt is projected into locking position is Serial No. 560,898. (No model.)

designed to be engaged by a latch F. Said latch extends transversely underneath the bolt, being pivoted to the case or shell at one end, while its freel end extends into an offsetchamber H upon the opposite side of the bolt and rests upon a coiled spring H', the stress of which is to throw said latch upwardly.

J is a guide for the latch.

K designates a keyhole which is formed in the cap or cover plate directly over the free end portion of the latch.

K is a suitable key.

L is a guard, which is pivoted to the outer surface of the cap or cover plate and normally covers the keyhole. A spring lc is placed in the eye of said guard around its pivot for the purpose of keeping it in place.

Zis a notch in the guard to indicate the position of the keyhole.

The guideway in which the bolt C slides is approximately cylindrical in cross-section, and the bolt can be inserted or removed from the end only, so that it cannot be removed by forcing the cap-plate. After such bolt has once been put in place a guard-loop M is placed over it, as shown. Said guard permits the bolt to slide freely therethrough sufficient to permit the necessary movement, but prevents any attempt to remove the bolt by reason of the fact that it will not admit the collar o therethrough. This guard usually forms the abutment for the spring E.

The above-described lock is designed to be secured to the frame of the machine by suitable clips or other means in such position that the bolt may be shot or projected through one of the wheels, preferably the sprocket-driving wheel. To lock the wheel, the knob or button E' is moved to project the bolt until the notch f comes into alignment with the latch F, which is at once engaged therewith through the action of its spring H'. To release the bolt, the keyv is placed against the guard L in the notch Z, and suchI guard is pressed back- .ward to expose the keyhole and admit the key. The inner end of the key coming in contact with the latch F, said latch is depressed and moved out of engagement with the bolt, whose spring E at once retracts it. 4

It is designed to provide the cap-plates with keyholes of different shapes, whereby each lock cannot be operated except by its own key.

IOO

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is"

l. In a bicycle lock, the combination with the chambered case or shell having an opening in one end and a removable, slotted capplate, of a bolt seated in the chamber of said shell and arranged to be projected through the end opening thereof, a spring coiled around a reduced portion of said bolt, and arranged to normally hold the same retracted, a pin fixed in said bolt and projecting through the slot of the cover plate, guards for preventing the removal of said bolt when the cap is removed, a catch extending transversely underneath thel said bolt and designed to engage a notch or recess thereof, one end of said catch being pivoted to the case or shell While its free end extends into an offset chamber thereof, a coiled spring seated under such free end, and a suitable key for depressing said catch against the tension of the said spring, substantially as specified.

2. The herein described bicycle lock, coinprising a case or shell adapted to be secured to the frame of a bicycle and having a cap plate provided With a keyhole, the bolt seated to the slide in a Way of the said case or shell, said Way being so shaped that the bolt can only be removed or inserted by a longitudinal movement, the collar on the inner portion of the said bolt, the guard through which the bolt Works, the retraction spring seated around said bolt between the said collar and guard, means for projecting the said bolt, the pivoted spring actuated latch therefor, and the pivoted spring actuated key-hole guard, together With a suitable key, all arranged and combined to operate substantially as and for the purpose described.

In testimony whereof I aiiix my signature in presence of two Witnesses.

JAMES E. SCOTT.
